Final answer:
Resistance is inversely proportional to the cross-sectional area of a conductor, meaning as the area increases, resistance decreases.
Step-by-step explanation:
Resistance is inversely proportional to the cross-sectional area of the conductor. As the cross-sectional area increases, resistance decreases, allowing more current to flow through the conductor. This relationship is crucial in understanding how the physical properties of a wire, such as its length, cross-sectional area, and material (or resistivity), affect its electrical resistance. According to Ohm's Law, resistance can also be seen as a factor that impedes current flow through a circuit due to collisions between moving charges and atoms within a conductor.
